The jewel of the solar system

Saturn

Saturn is the least dense planet — it would float on water. Its rings are ice and rock, from grains of sand to house-sized blocks.

Country around the board

Narrabri hosts the Australia Telescope Compact Array. Gulargambone and Goonoo Forest sit on Kamilaroi river country along the Castlereagh. “Goonoo” means a place of abundance — stars once timed the seasons in the river’s reflection.

Where to look

Search Google Maps for the planet plus the road or town. Boards are large, dark blue, and sit on the five approach roads — then Timor Road and Observatory Road for the inner worlds.
